18.11.2011. - 2012. matured in the atmosphere of Earth more than 37 billion tons of carbon dioxideThe record of the Earth's atmosphere pollution shocked scientists. In Germany, the published results of research experts of the Institute of sources of energy, which is renewable. According to the document, the content in the atmosphere of gases that cause the greenhouse effect, and is still rising.German scientists have focused on a record level of industrial emissions of these gases over the entire period of observation. 2011th The
Earth's atmosphere is past due more than 37 billion tons of carbon
dioxide, which climatologists believe the main cause of climate change
on the planet. About a quarter of the world's emissions of China made. Continue to follow the U.S. and Iran. Russia, according to the estimates of experts, has registered a reduction of emissions.Expert
of the Institute of Economic Forecasting RAN Porfirjev Boris explains
that, as the Russian economy has been a structural changes, was adopted
measures to increase energy efficiency of industrial production.- Strong reduction of the 1990-ies was a result of the economic crisis, however, after 2000. The Russian economy has been growing. Grew and emissions. In
doing so, the average annual growth rate of emissions was approximately
0.8 to 0.85 per cent per year, while the economy grew by about 4
percent a year. These
results are important structural changes that have occurred in recent
years at the expense of 20 branches, which require less energy. German research scientists have been published on the eve of the regular 18th UN Conference on the problems of global climate change. It will be held from 26 November to 7 December in Doha, capital of Qatar. It is assumed that the conference will work out a new agreement on the conservation of the Earth's climate. The document will replace the Kyoto Protocol, whose term expires this year of action.Kyoto critics are again highlighted the inefficiency of the agreement. Has not managed to reduce the emission of gases that cause the greenhouse effect. On the contrary, they have risen at twice the 1990-year. Conservationists point out that the Kyoto Protocol has not put anyone super tasks. The
main task was to draw the world's attention to the problem of climate
on Earth - says the expert of the Russian Federation Mikhail Julkin for industrialist and contractors.- It can be argued that the attempt failed. Yet developed countries are largely fulfilled commitments - reducing emissions by 5 percent compared to the level of the 1990th year. Emissions have been reduced in this part of the world. The other thing, as they grew in that part of the world, who had no obligations. I would point out that under the Clean Development Mechanism in developing countries there are about 4 thousand projects. This means that billions of tons of carbon dioxide in the atmosphere has not matured. I think this is a good result."Green" projects aimed at reducing emissions of industrial gases in the atmosphere, and work in Russia. They are the deflection of the supporting gas utilization, the implementation of new technology, the use of biofuels.Russia,
and beside Japan, Canada and many other countries, have made the
decision not to participate in the second period Kyoto agreement. And that, primarily because, as industry giants such as China and the U.S. are not even involved in it. However,
this does not mean that Russia back away from his obligations to low-carbon crossing the path of development, says a representative
of the Ministry of Economic Development Oleg Plužnikov.-
The Russian government is now considering adopting a variant of the
Interior liability limits emissions by 25 percent from the level of
1990-year. Here we are outside the EU. Hopefully, the EU will follow our example. I also hope that if the Doha such a goal if it is not checked, then it will be the least compliant. It is important that Russia is withdrawing from active attitude.Russia is interested in a new climate agreement include a maximum number of participating countries, - said the expert.

Russian scientists have made concrete which are not any terrible weather cataclysms. He not only is superior than other types of concrete, but is faster and hardens. This is particularly important for emergency repair of damaged bridges, dams, roads. In doing reconstruction work will now be able to perform in any weather conditions.At first glance, everything is as usual: sand, gravel and cement. But
instead of water is added to the solution of a special polymer fluid,
which provides the unique properties of concrete, says senior researcher
at the Russian University of Chemical Technology Mendeleyev Alexander
Nikitjuk:- We have examples where we have been working on a fairly low temperatures, down to minus 28 degrees Celsius. We evaluated the concrete during heavy rainfall and even under water.Special liquid polymer encapsulates all the components, connect them, and also protects against chemical reaction. This
is particularly noticeable if you drive down the samples in acid, says
researcher of the Russian University of Chemical Technology Mendeleyev
Jelena Pisarenko:- We take a piece of plain concrete and drop it in hydrochloric acid. The first seconds are often very severe reaction. Concrete starts to crumble. Also working with new concrete. No external signs react.This
property, say the authors, will be useful for repair of industrial
buildings, bridges and overpasses, which are constantly applied and
chemically aggressive liquid reagents, for example atifriz solutions for
roads.An important feature is another new concrete - the speed at which it hardens. It is indispensable for patching holes in the dams or on airport runways. In
order to gain strength plain concrete is required one month, and the
new salary concrete harden for half an hour and be stronger than regular
concrete, almost twice. Composite concrete universal. It can easily replace existing materials. In addition, scientists assure us that he will not be more expensive than ordinary cemen

Complex reasonsWhen you are in the 19 century
archaeologists began to excavate the ruins srednjoameričke first
appeared in numerous theories about the causes of catastrophic failure
May. However, new studies reveal that these reasons were numerous and complex - from war to drought and famine.According
to the latest research, presented in the new issue of the journal
Science, climate change played a key role in this process, and the Maya
themselves were partly responsible. Drought caused problems in agriculture and the instability that resulted in the war and the fall of the big cities. Following the political decline occurred is another great drought which prevented the recovery of civilization.This theory is not new, some scientists are already some evidence substantiated. However,
a new study researchers have so far the most accurate weather analysis
and scale droughts recorded in the caves, and they tried to agree on the
whole mosaic of stories about the collapse of the Maya.An
international team led by Kenneth Douglas, an anthropologist from
Pennsylvania State University took samples of stalagmites in a cave York
Baluma which was discovered near the ancient Mayan settlement. Stalagmites, which are formed by deposition of minerals in the water that drips from above, grow faster in more rainy years. Therefore, they are good indicators of climate conditions. One of the collected samples is so large and old that shows what were the weather changes in the past two centuries.The
study authors write that their analysis found that the early classical
period of May was unusually wet, wetter than the previous thousand
years. During this period, the 440th to 660, the population grew and cities have sprung up. All the important achievements of the Mayan civilization was in the 200-year Tinak. If stalagmites reveal that these two centuries was actually an anomaly. "Mayan
systems were based on samples of time in which there was plenty of
rain," said Kenneth, adding: "When they changed more samples could not
be maintained."

In Japan, created a device that allows you to run power objects of thought. Coffee looks like a hat with cables and sensors that respond to minute changes in blood pressure and brain impulses. way
during the experiment was a man who did not even move, just by thought,
could not run the wheelchair in the desired direction, moving curtains,
including switches off the TV and lights in the room. idea of the company that made ​​the machine to 2020. The mass production of a viable device. Coffee should make life easier for people with limited physical abilities.

The company was created by the Copenhagen software that allows users to control mobile view. ﻿This invention could provoke a revolution in the use of elektroniskih book readers and phones. ﻿

Think of that the next time you want to unlock your iPhone, do view. ﻿Denmark's The Eye Tribe has made it possible. ﻿She has developed a program to help control the view, which uses infrared technology. ﻿"We design the infrared light to the eye, and collects the reflected infrared camera. ﻿We have a program that can be very precise to say where the movie screen. ﻿And it helps control using views, "explains Alstrup Johansen, one of four Ph.D. from the University of Copenhagen to participate in the development program. ﻿This August they have collected 615. ﻿000 euros from private investors to make a prototype. ﻿

Johansen and his colleagues believe that the control looked through movement and the next big thing - Follow-touch control, which is now the standard when it comes to mobile phones. ﻿The program is described as "optional" form of control and as a step towards more "smarter" devices. ﻿He said that it could fundamentally change the way that games, entertainment, and even learning. ﻿"Imagine an electronic book that automatically turns a new page, so you know exactly when you read the whole page, imagine a phone that knows it's you when you look at it, and when you look to the side, it can be turned off," illustrated by Johansen. ﻿"When you play a game, she will know exactly where your attention is focused. ﻿So you can create amazing and more fun games. ﻿'.

Possible adverse effects

However, the question is what about the harmful effects such as eye strain. The
Central Association of opticians in Germany say that, since the
technology has not been tested, it is not known what effect it can have.
Dr. Thomas Liska, an ophthalmologist at the University Clinic in Hamburg, says perfusion infrared eyes can cause complications. "We know without any doubt that infrared light can damage the eye lens. And as more time is spent in front of mobile devices, such ray exposure time is critical, "says Liska. According to him, it is necessary to limit the exposure in order to avoid unnecessary risks. "Experiments would have to show that prolonged exposure dose emitted from these devices has no harmful effects," said Liska.

Alstrup Johansen, however, says that the eyes do not stress if you just look at the device in a natural way. "But
if you want more direct control, for example if you are playing a game
in which the goal, this is certainly something that we're used to. In some cases, there would be ways to train yourself to use the view control, when it is not natural, "says Johansen. The
company sees the Copenhagen view control in addition to other types of
control devices, such as voice control, which already exists in the
market, with varying degrees of success.

From patent to the actual users

The Eye Tribe want their technology to become ubiquitous. For this reason, and dropped free software kits to encourage developers to create applications that use this technology. "We believe that control of the sea This unique technology which can benefit people around the world. We want everyone to have access to this technology, "says Johansen. The company says it will make money from selling licenses to producers. before
them, but the big obstacles to convince big companies such as Apple and
Samsung, to the next generation of devices include components necessary
to control the view. "They need to make some small changes
to their own devices, but we see that there is great interest in the
market for all natural, so I think it's definitely possible," Johansen
optimistic. The company would not reveal his secret strategy for it. But if control of view become the next big thing in mobile telephony, then iPhone get a whole new meaning.

Astrophysicists working with data space telescope Fermi Gamma have found traces of light of the first stars in the universe. According
to scientists, "see" extragalactic radiation is very important, because
it allows you to peer into the most ancient history of the universe. Scientists suspect that this radiation originates from the epoch of 300,000 to 1 billion years after the Big Bang. Tracker has helped scientists obtain new information about the process of the oldest stars. Among
other things, according to their calculations, the speed of formation
of the first stars were much smaller than previously thought.

U.S. scientists have found a way to quickly and efficiently processing seaweed into biofuel. U.S. National Science Foundation reports that the thermal processing of raw materials took literally one minute. experiment's objective was to mimic the natural processes of marine microorganisms to convert into crude oil. As raw materials are taken unicellular green algae nannochloropsis. truth, experts say it is too early to talk about the practical use of a new method for making biofuels.
